So i got the sd mk2 last week. loving it but having some issues. it came with the 510 adapter and some 510 attys. one lasted a few hours and then gave out on me. tried cleaning did not help. the other one is working after boiling it. so happy about that. the issue that is bothering me though is that i got some extra 510 attys today form another company and they wont work at all on my sd. they work on my manual 510 battery but just wont work on the sd. can anyone help with this.
thanks in advance.
